No, this has not changed, Michel.

I failed to read the error message properly and garbled my report.  I
had CONFIG_SHELL set on the Solaris build but not on the Ubuntu
build.  However, the real problem is that gm2/tools-src/makeversion
is not passed through a shell but invoked directly and its specified
SOMETHING is /bin/sh.  When I changed this to /bin/bash, the build
succeeded on both systems.

On the other hand, sckt.c no longer compiles on Solaris for
gm2.paranoid.

and so on...

It seems that sys/socket.h is not being included.  (To be certain, I
put some garbage in the included scope and the compiler did not reach
it.)  However, this header file at some point includes the evil bcopy.
